Recharge Wrap-up: NEDC's NOx problems, autonomous Chevy Volts

The International Council on Clean Transportation (ICCT) found a significant difference in NOx emissions in Euro 6 diesel cars in NEDC and WLTC testing. While 88 percent of the cars tested met emissions standards for NEDC, NOx emissions averaged five times higher under WLTC, with only 27 percent of vehicles under the limit. WLTC is considered to be a more realistic driving cycle, using hot starts and factoring a higher top speed as well as harder and more frequent accelerations than the NEDC.

Employees will be able to use a carsharing app to reserve a car, which will then drive itself to the set destination. The project will allow GM to collect important data and experience to help the company more quickly develop autonomous driving technology.

The lithium-ion batteries used to power the EV were recycled from other Renault EVs. With the electric Trafic, Carwatt – a company that converts vehicles to use electric power – aims to demonstrate the "circular economy" of batteries, which can provide more value through a longer lifecycle. Read more in the press release below. Carwatt presents a unique automotive application for second-life batteries from electric vehicles. On the sidelines of the COP21 summit, in the Solutions Gallery running from 2 to 9 December 2015 in Le Bourget near Paris, Carwatt and its partners —Renault, Paris City Council, BPI France, the Ales Ecole des Mines Engineering School, and the Bobigny Business Campus — are showing a very special electric Renault Trafic. This prototype vehicle, the only one of kind in the world, is powered by second-life lithium-ion batteries recycled from Renault electric cars. Circular economy at work with electric vehicles When, over time, the batteries of a Renault electric vehicle fall the performance threshold specified for their initial automotive power duty (around 75% of initial capacity), they can still provide valuable service in "second-life" applications before end-of-life disposal at a recycling centre. Experiments are already under way on power storage applications, for example.

Best and Worst GM Cars

Oh yes, because we just love receiving angry letters from devoted Pontiac Grand Am enthusiasts, we have decided to go there. Based on a heated group Slack conversation, the topic came up about the best and worst GM cars. First of all time, and then those currently on sale, and then just mostly a rambling discussion of Oldsmobiles our parents and grandparents owned (or engineered). Eventually, three of us made the video above. Like it? Maybe we can make more. Many awesome GM cars are definitely going unmentioned here, so please let us know your bests and worsts in the comments below. Mostly, it's important to note that this post largely exists as a vehicle for delivering the above video that dives far deeper into GM's greatest hits and biggest flops, specifically those from the 1980s and 1990s. What you'll find below is a collection of our editors identifying a best current and best-of-all-time choice, plus a worst current and worst-of-all-time choice. Comprehensive it is not, but again, comments. -Senior Editor James Riswick Best Current GM Vehicle Chevrolet Corvette We were flying by the seats of our pants a bit in this first outing and my notes were similarly extemporaneous. When it came time to tie it all together on camera, I failed spectacularly. Thank the maker for text, because this gives me the opportunity to perhaps slightly better explain my convoluted reasoning. I chose the C8 Corvette because it's simply overwhelmingly good, and it's merely the baseline from which this generation of Corvette will be expanded.  While the Cadillac CT5-V Blackwing (more on that in a minute) is an amazing snapshot of GM's current performance standing and its little sibling so enraptured me that I went out and bought one, their existence is fleeting. Corvette will live on; forced-induction Cadillac sport sedans, not so much. So while all three are amazing machines when viewed in a vacuum, the Corvette stands above them as both a reflection of GM's current performance credentials and a signpost of what is to come. So, given the choice between the C8 and the 5V-Blackwing right now, I'd choose the C8. In 10 years, when the Blackwing is no longer in production and Corvette is in its 9th generation? Well, that might be a different story. Now, just pretend I said something even remotely that coherent when we get to the part of the video where I try to make an argument for the 5-V Blackwing as best GM car I've ever driven. Or just laugh at me while I ramble incoherently.

Fernando Alonso sputters in his Indy test

INDIANAPOLIS — Helio Castroneves and Fernando Alonso kept waiting around Wednesday. Now both international stars have some unfinished business to take care before qualifying for this year's Indianapolis 500. After enduring a rain delay of more than four hours then watching IndyCar regulars turn laps at Indianapolis Motor Speedway for two more hours, Castroneves and Alonso finally made it onto the track — but couldn't quite complete their refresher course. "Happy to be back here because this place is great," Alonso said after posting a fast lap of 218.690 mph — the slowest of the nine-driver evening session. "We were slow because the weather and some of the decisions people made on running time and things like that." He faced a bevy of problems in his first trip back to Indy since an impressive rookie performance in 2017. The rain delay forced organizers into rescheduling the one-day test, moving the rookie and refresher driver time from midday to the evening, cutting a significant amount of practice time for Alonso and the others. And when the green flag finally waved, Alonso's No. 66 car stalled in the warmup lane forcing the two-time Formula One champion from Spain to be towed back to pit lane where his crew worked feverishly to fix an electrical problem while sat in the cockpit. Eventually, he did get out and passed the first of two refresher phases. He'll have to wait until opening practice of the 500 on May 14 to pass the second. "It was frustrating for everyone because it was a brand new chassis and a brand new car, so we expected to run a lot," said Alonso, who drives for McLaren Racing. "If we could have had this at midday, you could work on your issues in the afternoon and then go out again." To put his day in perspective, Takuma Sato, the 2017 Indy winner from Japan, posted the fastest lap of the day at 226.993 mph and Colton Herta was the fastest rookie at 226.108. Castroneves, as usual, was good right from the start and posted a fast lap of 225.565. The three-time Indianapolis 500 winner looked smooth and fast on his favorite track and wasted no time passing the first phase. That much should have been expected from the popular Brazilian, who has recorded seven top-three finishes in 18 Indy starts and will make his season debut May 11 in the IndyCar Grand Prix. The weather and yellow flags prevented four of the five veterans — Castroneves, Alonso, Oriol Servia and JR Hildebrand — from passing phase two. Only Indy native Conor Daly made it.
